BEMOVABLE BULKHEAD.

ABulkheads, of which the following isv a specification.

' of the means for holding the bulkhead in` My invention relates to removable bulkheads and has for its principal object the provision of a construction of this character which will be highly efficient in use.

A further object of my improved construction is the provision of a removable bulkhead especially designed for use as a retaining wall holding merchandise or the like packed in a freight car tightly together, preventing the freight from falling and breaking while in transit or caused to fall by the sudden jarring and stopping of the car. y

Other objects will appear hereinafter.

The linvention conslsts in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a fragmentary longitudinal cross sectional view of a freight car showing my improved construction -mounted therein; j

Fig. 2 is a sectional view of my improved construction taken substantially on line 2-2 of Fig. 3; y

Fig. 3 is a fragmentary elevational view of my improved construction showing one operative position;

Fig. 4 is a fragmentary perspective View of a freight car partly in section showing my improved construction mounted thereln; Fig. 5 is a fragmentary elevational view showing vanother of the means for holding my improved construction in operative position;

Fig. 6 is a sectional detail view of. my improved construction, taken substantially on line 6-6 of Fig. 2, showing the holding lmeans embodied in the invention, extending laterally from the bulkhead; and

Fi 7 is a detail view of one of the spring mem ers embodied in my invention.

The preferred form of constructlon as Serial No. 456,118.

illustrated in the drawings comprises a bulkhead'7 formed of a plurality of wooden members 8 fixed rigidly together by wooden cross bars 9 or the like. On one side of the -bulkhead 7, adjacent each. of the outer ends,

a plurality of claw-shaped members 10 and 11 are swingingly mounted. The clawshaped vmembers 10 and 11 'are each formed from a single metallic rod, one end of which is :provided with prongs 12, the other end having a T-shaped head 13. Each of the laterally extending arms of the T-shaped head 18 is swingingly mounted on the bulkhead 7 by an eye bolt 13. Integrally formed on the T-shaped head 13, and extending laterally therefrom, is a lug 15 provided with a bore 16. Mounted on one of the eye bolts 13 is a spring member 17, one end of which passes through the bore 16 provided on the lug 15. The said spring member 17 is so arrangedthat when the claw-shaped member 10 or11 is past dead center it will be forced into operative posi-- tion or into a recess 17 provided on the bulk-A head 7. On the other side of the bulkhead 7, adjacent its upper corners, are other clawshaped members 18 being somewhat smaller than the claw-shaped members 1() and 11 and swingingly mounted on the bulk-head 7 in the same manner as the said clawshaped members 10 and 11. A recessl9 is provided on one of the wooden members 8 of the bulkhead 7, centrally located, arranged to receive a wooden vbar 20 or the like, one end of which butts against a block 20 secured to the floor of a freight car 21 serving as a central brace for the bulkhead 7.

In operation each freight caris provided with two of the bulkheads 7, located on each side of the door openings of the freight car, which are Iforced against the freight packed in said freight car. The claw-shaped members 10 and 11 are then swung into operative osition, the prongs 12 engaging the side wa ls of the freight car. By lightly tapping the claw-.shaped members with a hammer or any other suitable instrument the prongs will dig into the frame work of the car. The claw shaped members 13 'are then swung into operative position in the same manner as the claw-shaped member 10 and 11 preventing thev bulkhead from becoming loose as the freight settles which is caused by `the jarring of the car whilev in transit. Should the freight be caused to fall or press Specification of Letters Patent. Patented Dec, 27, 19,2L

forward, as the case maybe, against the bulkhead 7, the prongs 12 will be pushed dee er into the frame work of the car.

l en the car is used for the purpose of transporting grain or the like the bulkhead 7 can be used as a grain door. For this use of the bulkhead, a rod member 22 is secured to the upper part of the side wall and connected to one corner of the bulkhead 7 by a chain 23. The claw-shaped members are thrown out of operative position, into the recess 17, and the bulkhead is swung around closing the lower half of the door opening as shown b drawings. hen the bulkhead 7 is not in use, it can be placed in a corner of the car, lengthwise with theside wall, until ready for further use. l

While I have illustrated and described the preferred form of construction for carrying my invention intoA effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of the 'construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.-

Having described my invention, what I- claim as new and desire to secure by Letters Patent, is u y 1. A bulkhead comprising wooden members rigidly xed together; a, spring actuated member swingingly mounted on said bulkhead adapted to engage the side wall of a freight car retaining said bulkhead in `operative position, substantially as descrlbed. y y

2. A bulkhead comprising wooden 'members rigidly fixed together; a spring actuacted member, having prongs on one end swingingly mounted on said bulkhead adapted to engage the side wall of `a freight car retaining the said bulkhead in operative osition; anda recess in said wooden mem ers for the receptlon of said spring actuated member when out of .operative position,'substantially as describe 3. A bulkhead complrising woodenmembers rigidly fixed toget er; a T-shaped member swingingly mounted on said wooden member; ron integrally formed., on one end of said -shaped member adapted to engage the side -wall of a freight car retaining t e said bulkhead in operative position; and resilient means for forcing said T- shaped member into and out of operative pov sition, substantially as describe dotted lines in Fig. 4 of the- 4. A bulkhead comprising Wooden members rigidly fixed together; a T-shaped member Swingin ly mounted on said wooden members adapte to engage the side wall of a freight car; and a spring member mounted. on said bulkhead and passing through said T-shaped member arranged to throw said T-shaped member into and out of operative position, substantially as described.

5. A combination bulkhead and grain door formed from a plurality of wooden members; eye bolts mounted on said wooden members; a T-shaped member swingingly mounted on said eye bolts; prongs on said T-shaped member adapted to engage the side wall of a freight car retaining the said bulkhead and gram door in operative position; a spring member secured to one of said eye bolts and passing through said T-shaped member adapted to force the said prongs into and out of operative position; and a recess in said wooden members for the reception of said prongs when out of operative position, substantially as described.

6. n combination with a freight car having doorways and an overhead guide member; a combination bulkhead and grain door formed from a lurality of wooden members rigidly fixedp to ther; a chain member secured to said woo en members and slidably mounted on said guide member for swinging the said bulkhead and grain door longitudinally with relation to said freight car, when the said bulkhead or grain door serves as a grain door; and spring actuated means swingingly mounted on said bulkhead and grain door adapted to engage the side Walls of the said frelght car when the said bulkhead and ain door serve as a bulkhead, substantial y as described.

7. A bulkhead comprising a lurality of members fixed together; eye bolts mounted adjacent each corner of said bulkhead; T- shaped members swingably mounted on said eye-bolts adapted to engage the side walls of a freight car; spring members secured to said e e bolts and passing through said T- shape members adapted to force said T- shaped members into and out of operative position, substantially as described.

In testimony whereof I have signed my name to. this specification in the presence of -two subscribing witnesses.
